DESIGN OF A FAULT AND PARTIAL DISCHARGES LOCATION DEVICE FOR CABLE POWER NETWORK

In this thesis, a digital device for fault and on line partial discharge location is presented. The device employs the traveling wave method for two or multiple ends. The designed prototype shows interesting features connected to the low cost and to the possibility to collect data from different locations thus providing additional functionalities deriving from pre-fault and data analysis, relating the existence of defects to the subsequent fault event. The device also enables the acquisition of the temperature on the cable section where the sensor is installed. Such installation can also support DSO and TSO for carrying out both on-event and condition based maintenance, discovering the caus…

Identification of the novel Kawasaki 2014 GII.17 human norovirus strain in Italy, 2015

2015

Surveillance of noroviruses in Italy identified the novel GII.17 human norovirus strain, Kawasaki 2014, in February 2015. This novel strain emerged as a major cause of gastroenteritis in Asia during 2014/15, replacing the pandemic GII.4 norovirus strain Sydney 2012, but being reported only sporadically elsewhere. This novel strain is undergoing fast diversification and continuous monitoring is important to understand the evolution of noroviruses and to implement the future strategies on norovirus vaccines.

Tonometers and infectious risk: myth or reality? Efficacy of different disinfection regimens on tonometer tips

2006

Purpose To evaluate the adequacy of common disinfection regimens for disposable tonometer tips and assess if disinfection of reusable prisms or the use of disposable tips is preferable. Methods We used disposable tonometer tips, using the same material and tip diameter of standard Goldmann tonometer prism. Strains of Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Candida albicans were tested according to the European standard guidelines for disinfectants test. Antimicrobial effectiveness of the following disinfection practices has been assessed: dry wipe, Minuten wipes (Alpros), soaking in 3% hydrogen peroxide, 0.5% benzalkonium chloride, and 0.5% Pantasepts for 1, 5, …

Involvement of nitrate reductase and pyoverdine in competitiveness of Pseudomonas fluorescens strain C7R12 in soil

2001

ABSTRACT Involvement of nitrate reductase and pyoverdine in the competitiveness of the biocontrol strain Pseudomonas fluorescens C7R12 was determined, under gnotobiotic conditions, in two soil compartments (bulk and rhizosphere soil), with the soil being kept at two different values of matric potential (−1 and −10 kPa). Three mutants affected in the synthesis of either the nitrate reductase (Nar − ), the pyoverdine (Pvd − ), or both (Nar − Pvd − ) were used. The Nar − and Nar − Pvd − mutants were obtained by site-directed mutagenesis of the wild-type strain and of the Pvd − mutant, respectively. The selective advantage given by nitrate reductase and pyoverdine to the wild-type strain was as…

Performance assessment of a grid-connected mc-Si PV system made up of silicon material from different manufacturing routes

2013

Summarises the performance of an Elkem Solar photovoltaic (PV) system installed in the Sunbelt Region (between 35 North and 35 South) in Hyderabad, India, which has been fully operational since August 2012. The PV system consists of 28 multicrystalline silicon PV modules made from the standard Siemens process and from material produced by a metallurgical route - the Elkem Solar Silicon (ESS™) process. A comparative performance study of the ESS™ modules with respect to standard polysilicon has been carried out under the various climatic and solar radiation conditions at the location. The present study suggests that the ESS™ PV modules have a slightly better performance than standard polysili…

Prospective analysis of infectious disease surveillance data using syndromic information.

2014

In this paper, we describe a Bayesian hierarchical Poisson model for the prospective analysis of data for infectious diseases. The proposed model consists of two components. The first component describes the behavior of disease during nonepidemic periods and the second component represents the increase in disease counts due to the presence of an epidemic. A novelty of our model formulation is that the parameters describing the spread of epidemics are allowed to vary in both space and time. We also show how syndromic information can be incorporated into the model to provide a better description of the data and more accurate one-step-ahead forecasts. These real-time forecasts can be used to …

Burnout and Online Medical Education: Romanian Students in Lockdown and Their Residency Choices.

2022

The primary aim of the study was to investigate the prevalence of burnout in Romanian medical students during the COVID-19 pandemic using the Maslach Burnout Inventory-General Survey for Students (MBI-GS(S)). The presence of burnout was assessed based on Exhaustion (EX), Cynicism (CY) and Professional Efficacy (PE) subscales. The secondary aim of the study was to identify the presence of intentional shift in medical specialty compared to their initial pursued choice within the population investigated. Data was collected online at the end of 2020 and beginning of 2021 through a licensed, customized MBI-GS(S) questionnaire from a sample of 126 Romanian medical students at the two leading medi…

Pustular lesions and itching in a couple of young migrants

2022

Two teenage illegal migrants from Bangladesh coming from a Libyan port arrived at Lampedusa Island-Italy. The health authorities, having noticed the presence of pustules on the limbs and genitals, suspecting a monkeypox virus infection, have urgently transferred them to the University Hospital of Palermo. They mentioned itching and prior sexual contact. On inspection, itching lesions and pustular lesions with central crusted umbilication and erythematous bases were detected. One of them had also fever and increased c-reactive protein. A real-time polymerase chain reaction assay on vesicle swabs to research monkeypoxvirus DNA and HIV serology was performed for both patients.
